Intraoperative CT as a registration benchmark for intervertebral motion compensation in image-guided open spinal surgery

摘要

PurposeAn accurate and reliable benchmark of registration accuracy and intervertebral motion compensation is important for spinal image guidance. In this study, we evaluated the utility of intraoperative CT (iCT) in place of bone-implanted screws as the ground-truth registration and illustrated its use to benchmark the performance of intraoperative stereovision (iSV).
